>What makes you so sure?

"Manc"hester. Thought that would have been obvious to a dapper chap like you.

>Why, cos I wasn't born within sound of the Liver Building clock?

Nope. Because a real Scouser knows who/what a Manc is and how to spell it.

>I suppose they "back-fire" where you are too, and get mistaken for gun shots.

The big problem in Liverpool nowadays is increasing gun crime. The things you Scousers will do for a free shell-suit.
